Is it necessary to build my iphone app with armv7 architecture?

Or is armv6 good enough / can newer devices run an armv6 release? Do I have to build both to get all devices? Does Unity profit from armv7?

I'm just guessing here, but it seems like Unity itself is building armv6 assembly. So I doubt you'll see any speed increases by using armv7 compiling. (Which is a shame since armv7 on newer devices is faster, and they added faster floating point support to thumb code.)

Obviously the newer devices can run armv6 code, as otherwise they wouldn't be able to run the old apps.

I'm assuming the reason you're bringing this up is because of this warning:

warning: building for SDK 'Device - iPhone OS 3.2' requires an armv7 architecture.

Of course it's just a warning and not an error. I turned off building for armv7 by using "standard" architectures (armv6 only) and it still runs on my iPad, so I'm guessing it can be ignored.

(I don't really have an answer for you.)

Its a good indication and makes sense - I'm not asking because of the warning, I'm just asking because if I want to stay under the 20 meg limit, I can't compile with both architectures. But since Unity is building armv6, armv7 doesn't make much sense... And that newer devices need to run older apps makes also very much sense.
